PC.11 Point clouds adapter for BimCraft

Same engine, thin adapter (build for Super); E57/PLY/PCD inputs through pointcloud.js.

adapters-09 2026-11-06: The Point clouds add-on now runs in BimCraft over the same lib/pointcloud engine (byte-identical copy) and the same panels as CivilCraft, with a thin host adapter: the cloud is drawn in the IFC 3D view with levels of detail and a point budget, clean with undo, section strip, ground classification, and E57, PLY, PCD, PTX and XYZ through the app's own readers (thinned to 3 million points). window.ccPointCloud.cloud is the open cloud for scan to BIM. Tested in the real page on the 360,200-point made-up site (tools/pointcloud-adapters/browser.mjs --app bim, 20/0). Not tried on a real scan, in Studio or on a GPU; ground building, contours, stockpile volumes and orthomosaics stay in CivilCraft.
